Easter is fast approaching, so it's the perfect time to try some of our Easter STEM Challenges! We've been busy testing these for you over the last couple of weeks and would LOVE to see the creations of your little scientists, so do share photos with us on Facebook, Instagram or Twitter. I've also got 100s more easy everyday science and STEM activities you might like.
Top tip for STEM Challenges
My biggest tip for a successful STEM Challenge is to keep it simple. Simple STEM challenges are much easier for kids to complete, and as a parent, I know how difficult it can be if you need to go out and buy lots of science materials.
Easter STEM Challenges
Eggy Zip Wire
The idea behind this activity is to build a harness to transport an egg down a zip wire. This is a great activity for learning about friction and changing gradients. To investigate, try changing the type of string used to make the zip wire. A rougher string means more friction between the harness and zip line.
We usually set this up outdoors between two trees, but it works well inside, too.
Save the Egg
For this activity, children need to wrap an egg so well that it survives a drop down the egg chute. We used a long cardboard tube for our chute, but if you don't have a tube, drop it from shoulder height.
This is a great activity for making use of recycled materials, too.
Remember to drop all the packaged eggs from the same height to make it a fair test.
How much does an egg weigh?
Using a small balance scale, investigate how many plastic eggs weigh as much as a chocolate egg. Children can also measure and compare different types of eggs.
Magnet Powered Egg Cars
Put a magnet inside a plastic egg and use magnet power to make a car move. This is a brilliantly simple Easter STEM challenge!
Eggy Toothpick Towers
Try to build a tower strong enough to support an egg using toothpicks and plasticine. This activity is good for encouraging children to think about strong shapes.
Catapult an Egg
Build a craft stick catapult to catapult a plastic egg. We've been making egg-shaped targets to shoot the eggs through, too!
Egg Chain Reaction
We love making chain reactions! For this Easter version, we created a chain reaction using a chocolate egg instead of a ball. We used dominoes, a plastic pipe and a toy car, but you can use anything you have around the house.
A chain reaction is a great open-ended STEM challenge with lots of opportunities to be creative and inventive.
Pneumatic opening egg
This simple pneumatics based STEM challenge uses two syringes and a piece of plastic tubing to open a shoebox decorated like a chick inside an egg.
Finally, I've created a set of easy Easter STEM Challenge printable cards you might like!
